"The fear of suffering is worse than the suffering itself ... no heart has ever suffered when it goes in its search of its dreams."
One of the famous quotes from The Alchemist's novel, Paulo Coelho.
Fear is a very human reaction, part of our natural survival instinct, but sometimes our feelings of fear for something happen in situations where there is no real danger.
The fear will only make us fail, even fail before we start fighting. Remember that the thought of a thing is often worse than it is.
In these situations we must learn to control our fears.
Never underestimate your potential.
